The 1.1 download sites are for versions prior to this fix. Looking in the source code archive, can only get versions prior to this fix. The bug report indicates fixed in version 1054175 of the code.
The current Tomcat/JSTL SVN repository appears geared to deliver JSTL 1.2 code.
We are experiencing the issue described in the bug report. We don't want to go forward yet to 1.2 and going back to 1.0 causes other issues. Is anyone able to point me at a source download for 1.1 with this fix, happy to build on our site. Or, better still, a jar file ready to go.
